TQKaZZ whomt may concern:

Beit known that I, JAMES E. HENRY, a

. citizen of theUnited States, residin at New y for effecting itsretention in its different po` ing of the tire upon the vulcanizingVsurface of the oven. i y

Another objectof the invention is to prolvide a vulcanizer lwhich willconsistl of a vulcanizing oven having a heatlng surface and a tireplant, movable with respect-to the heating surface land provided withmeans `sitions of adjustment. Y

Y Another object of the invention: to prof `vide a vulcanizingapparatus" which is principally in the form of an attachment capable ofconnection with a vulcanizing oven or l mold of any suitable well knownform.

With the above and other objects in view which will appear as thenaturerof the in- Y vention is better understood, the sameA con.-

sists in the improved construction andnovel arrangements of partswhichwill hereinafter be fully described and lparticularly pointed out in theclaims.

In the accompanying drawing, has been illustrated, a single andpreferred form of the invention, it being, however, understood that nolimitations are necessarily made to the precise structural detailstherein exhibited, but that changes, alterations and modificationswithin the scope of the claims may i be resorted when desired.

Figure 1 is a perspective view of the vulcanizer showing the clamplowered in full lines and raised in dotted lines.

Figure 2, is a horizontal section on the line 2 2 of Figure l.

In carrying the invention into practice, use is made of an attachingplate 5 adapted to be secured by means 6, to one side of a.

vulcanizing oven or mold 7 and as illustrated, the mold is of thecustomary variety adapted to be heated by steam whlch is introduced tothe chamber of the mold by way oi a steam supply connection 8. The moldSpecification of Letters VPatent. Patented 3131;, 2 8; animation undoctober 25, 1921. serial No. 510,2;4. i

is provided with an arcuatechannel 9-whose cross sectional formcorresponds substantially with the cross sectional Shape of' an ordinarypneumatic casing,

Arranged to operate in the-,channel 9is an arcuate clamp or pressingshoe 10, the cross sectional form of which Vcorresponds with theconfiguration of the said channel so that the parts operatively adaptthemselves to the tire to be vulcanized. This clamp is provided with abracket 11,- which carries a "en tical rack bar 12 slotted at 13 toaccommo-vv date guide studs 14 which are secured-to the plate 6. These.guide studs are also associated'with a clampin plate 15 so thatthe rackbar is free to sli e between it and the aforesaid attaching plate 6.

Located at one side of the rack bar is an operating gear 15 whose teethintermesh with the teeth 16 of saidl rack bar so that when the gear isturned, the bar can be respectivelymoved in two directions, causing thepressing shoe or clamp 10 to be moved with relation to the walls of themold channel 9. This gear is provided with a crank handle 16 whereby itcan beconveniently operated by hand. In order that the pressing shoe orc lamp 10 can be retainedin its diiferent positions of adjustment, useis made of a locking dog 17 having-a nose 18 which' engages with theteeth of the kgear 15 as shown in full-lines in Figure 1. When this noseis accordingly engaged with the gear, the latter is positively lockedagainst retrograde motion and the shoe or clam 10 is held in firmpressingconfnement wlth the casing of the tire during the cooking orvulcanizing process. When this dog is turned on its pivot 19, so thatits nose 20 is brought` into engagement with the teeth of the gearingthe clamping shoe 10 is held in an elevated position as shown in dottedlines in Figure 1.

.From the construction set forth, itwill be observed that by simplymanipulating the dog 17, the gear 15 can be turned in the re-v quireddirection to effect adjustments of the pressing or clamping shoe 10.When the shoe is adjusted to the position shown in dotted lines inFigure 1', free access is had to the space between the shoe and the moldchannel 9 and in consequence thereof, the tire can be shifted to changeits position with respect to the mold as will be understood.

When the gear is turned in the opposite .Firm Contact with the easing soas to hold the same firmly against the Walls of the channel 9 wherebyaction of vviiloanzing heat. In the full line position shown in Figurel, the dog 17 acts to retain this firm pressing engagement o't Y Y saidshoe with the easing.

While I have described the use 'of the (ieviee in connection with theoasings of auto-u mobiles, it is equally useful in the vulcanizing ofinnertubes, etc.

While I have herein fully shown and described and have pointedv out inthe apit is eventuallysubjeeted "to the speetively movin@ the. clamp intWo What is claimed as'neW is f 1. A vuleanizer comprising aniovenstructure having a vulcanizing surface, a clamp o o-acting With saidsurface, means for re- POSI- tions, and means position ofv adjustment,the moving Vmeans embodying a gear, and a rack bar carried by the clampand oo-aeting with the gear.

2. A vuloanizer Vcomprising an oven structure having a vuleanizingsurface, a clamp eo-aeting with said surface, means for respectivelymoving the clamp in two positions, and means `for holding the el amp inits position of adjustment, the moving means embodying a gear, and arack bar carried by the clamp and co-aeting with the gear, the

holding means comprising Aanadjustable dog co-aeting with said gear.

In testimony whereof I have axed my signature.
